Abstract
BACKGROUND There is no standard treatment recommended at category 1 level in international guidelines for subsequent therapy after cyclin-dependent kinase 4/6 inhibitor (CDK4/6) based therapy. We aimed to evaluate which subsequent treatment oncologists prefer in patients with disease progression under CDKi. In addition, we aimed to show the effectiveness of systemic treatments after CDKi and whether there is a survival difference between hormonal treatments (monotherapy vs. mTOR-based). METHODS A total of 609 patients from 53 centers were included in the study. Progression-free-survivals (PFS) of subsequent treatments (chemotherapy (CT, n:434) or endocrine therapy (ET, n:175)) after CDKi were calculated. Patients were evaluated in three groups as those who received CDKi in first-line (group A, n:202), second-line (group B, n: 153) and ≥ 3rd-line (group C, n: 254). PFS was compared according to the use of ET and CT. In addition, ET was compared as monotherapy versus everolimus-based combination therapy. RESULTS The median duration of CDKi in the ET arms of Group A, B, and C was 17.0, 11.0, and 8.5 months in respectively; it was 9.0, 7.0, and 5.0 months in the CT arm. Median PFS after CDKi was 9.5 (5.0-14.0) months in the ET arm of group A, and 5.3 (3.9-6.8) months in the CT arm (p = 0.073). It was 6.7 (5.8-7.7) months in the ET arm of group B, and 5.7 (4.6-6.7) months in the CT arm (p = 0.311). It was 5.3 (2.5-8.0) months in the ET arm of group C and 4.0 (3.5-4.6) months in the CT arm (p = 0.434). Patients who received ET after CDKi were compared as those who received everolimus-based combination therapy versus those who received monotherapy ET: the median PFS in group A, B, and C was 11.0 vs. 5.9 (p = 0.047), 6.7 vs. 5.0 (p = 0.164), 6.7 vs. 3.9 (p = 0.763) months. CONCLUSION Physicians preferred CT rather than ET in patients with early progression under CDKi. It has been shown that subsequent ET after CDKi can be as effective as CT. It was also observed that better PFS could be achieved with the subsequent everolimus-based treatments after first-line CDKi compared to monotherapy ET.

Abstract
OBJECTIVE The aim of the study is to compare the efficacy and safety of 3 chemotherapy regimens used as first-line treatments in the real-life management of metastatic pancreatic cancer. METHODS A total of 218 patients were included in this multicenter study. Gemcitabine (Gem, n = 71), gemcitabine-cisplatin (Gem-Cis, n = 91), and FOLFIRINOX (a combination of leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin [FFX], n = 56) treatments were compared. RESULTS Overall response rate was significantly higher in the FFX group (50.0%) than in the Gem (28.2%) and Gem-Cis (27.5%) groups (P = 0.010). Median progression-free survival (8.4 vs 4.6 and 5.5 months, respectively, P < 0.001) and overall survival (16.4 vs 8.1 and 8.7 months, respectively, P = 0.002) were significantly longer in the FFX group than in the Gem and Gem-Cis groups. Toxicity of any grade was noted in 46 (64.8%), 56 (61.5%), and 49 (87.5%) patients in the Gem, Gem-Cis, and FFX groups, respectively (P = 0.003). CONCLUSIONS In our study, FFX regimen provides a significant advantage over the other treatment regimens in terms of response rates and survival. Treatment toxicity was more frequent but manageable with the FFX regimen.

Abstract
INTRODUCTION Alectinib is an effective second-generation ALK tyrosine kinase inhibitor (TKI) used in the first-line treatment of patients with advanced ALK-positive NSCLC. Recent studies demonstrated that the percentage of ALK-positive tumor cells in patient groups receiving crizotinib might affect outcomes. This study aimed to investigate whether the percentage of ALK-positive cells had a predictive effect in patients with advanced NSCLC who received first-line Alectinib as ALK-TKI. MATERIALS AND METHODS This retrospective study included patients with advanced-stage NSCLC who received alectinib as a first-line ALK-TKI and whose percentage of ALK-positive cells was determined by FISH at 27 different centers. Patients who received any ALK-TKI before alectinib were not included in the study. Patients were separated into two groups according to the median (40%) value of the percentage of ALK-positive cells (high-positive group ≥ 40% and low-positive group < 40%). The primary endpoint was PFS, and the secondary endpoints were OS, ORR, and PFS of the subgroups based on different threshold values for the percentage of ALK-positive cells. RESULTS 211 patients were enrolled (48.3% female, 51.7% male) to study. 37% (n = 78) of the patients had received chemotherapy previously. After a median of 19.4 months of follow-up, the median PFS was not reached in the high-positive group (n = 113), but it was 10.8 months in the low-positive group (n = 98) (HR 0.39; 95% CI 0.25-0.60, p < 0.001). The median OS in the high-positive group was not reached, whereas it was 22.8 months in the low-positive group (HR 0.37; 95% CI 0.22-0.63, p < 0.001). ORR was significantly higher in the high-positive group (87.2 vs. 68.5%; p = 0.002). According to the cut-off values of < 20%, 20-39%, 40-59%, and ≥ 60%, the median PFS was 4.5, 17.1, and 26 months, respectively, and could not be reached in the ≥ 60% group. CONCLUSION Our study demonstrated that the efficacy of alectinib varies significantly across patient subgroups with different percentages of ALK-positive cells. If these findings are prospectively validated, the percentage of ALK-positive cells may be used as a stratification factor in randomized trials comparing different ALK-TKIs.

Abstract
Aims: In this multicenter study, the authors aimed to determine the real-life efficacy and safety of first-line alectinib. Materials & methods: This retrospective trial included advanced-stage, ALK-positive non-small-cell lung cancer patients who were treated with first-line alectinib in terms of ALK-tyrosine kinase inhibitors, regardless of previous chemotherapy. The co-primary end points were progression-free survival both for all patients and for the treatment-naive population. The secondary end points were overall response rate, overall survival, rate of CNS progression and safety. Results & conclusion: A total of 274 patients (n = 177 for treatment-naive patients) were enrolled in the study. The median progression-free survival was 26 and 28.8 months for all patients and the treatment-naive group, respectively. The overall response rate, CNS progression rate and 1-year overall survival ratio were 77.9, 12.4 and 77%. Alectinib is a highly effective therapy with a favorable safety profile.

Abstract
BACKGROUND In chronic Hepatitis B virus (HBV) infection, certain individual and viral characteristics such as advanced age, presence of hepatic steatosis (HS), normal ALT levels, initially negative HBeAg and HBV DNA, and genotype of the virus are associated with HBsAg seroclearance and seroconversion. Herein, we report the results of our study evaluating the association between hepatosteatosis and HbsAg seroconversion. METHODS The clinical and biochemical data of patients with CHB and hepatosteatosis (HS) (HBsAg seroconversion, n:52, and non-HbsAg seroconversion, n:352), and the rate of development of HBsAg seroconversion were evaluated. RESULTS We collected data from 404 patients with HBeAg negative CBH (mean age ± SD: 36.2 ± 11 years; 223 [55.2%] men, 181 [44.8%] women). The mean age at diagnosis of disease was 36.2 ± 11 years. The mean duration of the disease was 10.6 ± 7 years. Seroconversion developed in 52 patients (12.8%) with serum HBsAg positive (mean ± SD: 12.7 ± 5.8). Elderly age and the duration of disease time were significantly associated with seroconversion (P < .001). The presence of serum HBsAg seroconversion was significantly associated with hepatosteatosis (OR: 3.06, 95% CI 1.64-5.71, P < .01). Serum HBsAg seroconversion was more frequent in patients with mild HS than patients with moderate-severe HS (P = .04). In multivariate regression analysis, the presence of HS was found to be an independent factor predicting the development of HBsAg seroconversion (OR: 2.07 95% GA:1.07-4.0 P = .03). CONCLUSION The presence of mild HS in HBeAg negative chronic hepatitis B patients contributes to HBsAg seroconversion. Further studies are required to better understand the relationship between steatosis and HBsAg seroconversion.

Abstract
PURPOSE In the ToGA trial for HER2-positive advanced gastric cancer, cisplatin plus fluoropyrimidine was given for 6 cycles; trastuzumab was given until disease progression. However, there is a lack of real-life data about trastuzumab maintenance after 6 cycle chemotherapy. This study aims to present real-life data of trastuzumab ± capecitabine maintenance after 6 cycles of platinum, fluoropyrimidine, and trastuzumab in non-progressive patients. METHODS This is a retrospective multicenter study of the Turkish Oncology Group. A total of 35 HER2-positive, inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma patients being non-progressive at the end of 6 cycle chemotherapy and being given trastuzumab ± capecitabine as maintenance treatment were included from sixteen oncology centers. Baseline characteristics, objective tumor responses, progression free and overall survival data, and toxicities were determined. RESULTS About 68% of the patients were given CF, and 32% were given FOLFOX with trastuzumab as the first-line treatment. The best response in 6 cycle chemotherapy was complete 8 (22%), partial 24 (68%), and stable disease 3 (8%). All patients had trastuzumab maintenance (median cycle 13; range 7-51), and 49% of the patients had capecitabine with trastuzumab (median capecitabine cycle 6; range 2-30). The median PFS of the patients was 12.0 months (95% CI 10.3-13.7), and median OS was 17.4 months (95% CI 15.2-19.5). There were 2 patients with grade 1 cardiotoxicity. CONCLUSION Trastuzumab maintenance ± capecitabine after 6 cycles of trastuzumab plus combined chemotherapy treatment revealed efficacy and safety in non-progressive HER2-positive advanced gastric cancer.

Abstract
PURPOSE Taxane-containing combinations are recommended for the first-line therapy of advanced gastric cancer. It is not known which chemotherapy regimen is the best with trastuzumab for HER2-positive patients. The aim of this study was to compare taxane-containing intensified chemotherapy versus standard chemotherapy in combination with trastuzumab in the first-line treatment of HER2-positive advanced gastric adenocarcinoma. METHODS This study is a retrospective multicenter study of the Turkish Oncology Group. A total of 130 HER2-positive patients with inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma being given chemotherapy plus trastuzumab as the first-line treatment were included from 16 different oncology centers. Trastuzumab combination with intensified chemotherapy including taxane or standard chemotherapy was compared in terms of progression-free survival (PFS), overall survival (OS), and toxicity. RESULTS There were 108 patients in the standard and 22 patients in the intensified chemotherapy group. PFS of the standard and intensified group were 5.6 months (95% confidence interval [CI] 4.8-6.4) and 5.3 months (95% CI 2.6-8), respectively (p = 0.70). OS of the standard and intensified group were 11.1 months (95% CI 8.3-13.9) and 15.2 months (95% CI 12.7-17.7), respectively (p = 0.03). Repeated analysis excluding patients given any previous therapy revealed similar results. The intensified group had more fever and febrile neutropenia. CONCLUSION Trastuzumab combination with intensified chemotherapy provides better OS in first-line treatment of HER2-positive advanced gastric cancer. Further large-scale studies should be performed in HER2-positive patients.

Abstract
This study aimed to determine the levels of milk cell total protein (TP), reduced nicotinamide adenine dinucleotide phosphate (NADPH), total glutathione (tGSH), activities of glucose-6-phosphate dehydrogenase (G6PD) and glutathione peroxidase (GPx) in subclinical mastitic cows. Milk from each udder was collected and grouped by the California Mastitis Test. Then, a somatic cell count (SCC) was performed, and the groups were re-scored as control (5-87 × 103 cells), 1st group (154-381 × 103 cells), 2nd group (418-851 × 103 cells), 3rd group (914-1958 × 103 cells), and 4th group (2275-8528 × 103 cells). Milk cell TP, NADPH, tGSH levels, G6PD, and GPx activities were assessed. Microbiological diagnosis and aerobic mesophyle general organism (AMG, cfu/g) were also conducted. In mastitic milk, TP, NADPH, and tGSH levels, and G6PD and GPx activities were significantly reduced per cell (in samples of 106 cells). In addition, milk SCC was positively correlated with AMG (r=0.561, p⟨0.001), NADPH (r=0.380, p⟨0.01), TP (r=0.347, p⟨0.01) and G6PD (r=0.540, p⟨0.001). There was also positive correlation between NADPH (r=0.428, p⟨0.01), TP (r=0.638, p⟨0.001) and AMG. NADPH was positively correlated with TP (r=0.239, p⟨0.05), GPx (r=0.265, p⟨0.05) and G6PD (r=0.248, p=0.056). Total protein was positively correlated with tGSH (r=0.354, p⟨0.01) and G6PD (r=0.643, p⟨0.001). There was a negative correlation between tGSH and GPx activity (r=-0.306, p⟨0.05). The microbiological analysis showed the following ratio of pathogens: Coagulase-Negative Staphylococci 66.6%, Streptococcus spp 9.5%, Bacillus spp 9.5%, yeast 4.8%, and mixed infections 9.5%. As a conclusion, when evaluating the enzyme and oxidative stress parameters in milk, it is more suitable to assign values based on cell count rather than ml of milk. The linear correlation between the SCC and AMG, milk cell NADPH, TP and G6PD suggests that these parameters could be used as markers of mastitis.

Abstract
Objective: We aimed to evaluate the effectiveness of an mEOX (modified epirubicin, oxaliplatin plus capecitabine) regimen as second line therapy after failure of mDCF (modified docetaxel, cisplatin plus fluorouracil). Methods: Gastic cancer patients for whom first-line therapy was unsuccessful and who subsequently received mEOX (epirubicin 50 mg/ m2 on day 1, oxaliplatin 85 mg/m² day 1 and capecitabine twice-daily dose of 625 mg/ m2, p.o. for 2 weeks) every 3 weeks until disease progression or unacceptable toxicity, were retrospectively analyzed. Results: The study population comprised 129 cases with a median age of 55 years (range= 27-78), the majority being male (76 %). Most (75.2%) had ≥ 2 sites of metastasis. The median number of chemotherapy courses was five (range= 2–9). Forty-nine achieved a partial response and 33 showed stable disease, resulting in a ORR (overall response rate) of 38% and a DCR (disease control rate) of 63.6%. The most frequent features of grade 3-4 hematological and non-hematological toxicity were neutropenia (8.5%) and nausea/vomiting (5.4%). None of the patients suffered death due to toxicity. The median PFS was 4.7 months (95% CI, 4.1–5.3) and the OS was 7.4 months (95% CI, 6.3–8.5). On multivariate analysis, age ≥ 60 years and ECOG performance status (0-1) were independent prognostic factors affecting PFS and OS. Conslusions: In advanced gastric cancer patients, who progress after first line chemotherapy and have an ECOG performance status of 0-1, mEOX is a well tolerated triple regimen associated with a promising OS and PFS.

Abstract
PURPOSE To evaluate the role of melatonin, an antioxidant agent, in diabetic oxidative stress and vascular damage. METHODS Diabetes was induced in 21 male Wistar rats by intraperitoneal (IP) administration of streptozotocin and then the rats were equally and randomly allocated to diabetic, melatonin, and vehicle groups. Seven healthy normal rats with similar features comprised the control group as the fourth group. All animals were followed for 12 weeks. The melatonin group received IP melatonin daily and the vehicle group received 2.5% ethanol IP at the last month. At the end of 12 weeks, the rats were killed and retinas were harvested. The retinas were investigated for the existence of hypoxia-inducible factor 1-α (HIF-1α), vascular endothelial growth factor A (VEGF-A), and pigment epithelium-derived factor (PEDF) by ELISA. Retinal oxidative stress is quantitated by measuring nitrotyrosine and malondialdehyde levels. Retinal immunohistochemistry with antibody against CD31 antigen was carried out on retinal cross-sections. For statistics, ANOVA test was used for multiple comparisons. RESULTS Hyperglycemia increased retinal oxidation as measured through levels of nitrotyrosine and malondialdehyde. Diabetic retinas are also associated with abnormal vascular changes such as dilatation and deformation. HIF-1α, VEGF-A, and PEDF were all increased because of diabetic injury. Melatonin showed a potential beneficial effect on retinopathy in diabetic rats. It decreased retinal nitrotyrosine and malondialdehyde levels, showing an antioxidative support. The vasculomodulator cytokines are decreased accordingly by melatonin therapy. Melatonin normalized retinal vascular changes as well. CONCLUSION Melatonin may show some advantage on diabetic vascular changes through decreasing oxidative stress and vessel-related cytokines.

Abstract
1. The objective was to investigate a possible contribution of a nerve-derived hyperpolarizing factor to the differences between non-adrenergic non-cholinergic (NANC) nerve-mediated relaxations in different states of active tone in the rat gastric fundus. 2. NANC relaxations induced by electrical field stimulation (ES: 0.1, 0.5 and 1 Hz; 25 V; 1 ms; 10 s) in 40% contracted strips (S40) were greater when compared with those in 80% contracted strips (S80). 3. ES-induced relaxations were effectively attenuated by N(omega)-nitro-L-arginine (L-NNA; 100 microm) in S40 and S80. Percentage reduction of the responses obtained in the presence of L-NNA in S40 group was less than that of S80. 4. In S40 group, nifedipine (0.5-1 microm) and verapamil (0.5-1 microm) inhibited the responses to 0.1 and 0.5 Hz. Nifedipine (1 microm) and verapamil (0.5 microm) caused no change in the responses to ES in S80. 5. In S40, when L-NNA (100 microm) and nifedipine or verapamil, either in 1 microm concentration, were administered together, the inhibition on the electrical relaxations were more than that of each drug alone. 6. In conclusion, NANC nerve-mediated relaxations are increased when studied in an active state of 40%, and a factor, sensitive to nifedipine seems to be responsible for this distinction.

Abstract
The involvement of nitric oxide (NO) and vasoactive intestinal polypeptide (VIP) in nonadrenergic noncholinergic (NANC) nerve-induced relaxation and the interaction between NO and VIP were investigated in the mouse gastric fundus. N(omega)-nitro-L-arginine (L-NOARG; 100 microM) completely inhibited the NANC relaxations induced by electrical stimulation (ES) (0.5, 1, 2, 4, and 8 Hz; 25 V; 1 ms; 15-s trains). Hemoglobin (20 microM), hydroxocobalamin (100 microM), and 1H-[1,2,4,]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ; 10 microM) diminished ES-induced relaxations, but alpha-chymotrypsin (10 U/ml) and VIP antiserum (1/200 dilution) had no effect on NANC relaxations. L-NOARG (100 microM) did not have any effect, whereas ODQ (10 microM) attenuated sodium nitroprusside (SNP; 100 nM)-induced relaxations. alpha-Chymotrypsin (10 U/ml) had no effect on the response to SNP. Furthermore, alpha-chymotrypsin (10 U/ml) abolished and VIP antiserum (1/200 dilution) diminished VIP (50 nM)-induced relaxations. L-NOARG (100 microM) caused an inhibition of VIP-induced relaxation that was reversed by L-arginine (1 mM) but not by D-arginine (1 mM). Similarly, ODQ (10 microM) inhibited the responses to VIP. 2-Amino-5,6-dihydro-6-methyl-4H-1,3-thiazine (5 microM) had no effect on these relaxations. L-NOARG (100 microM) and ODQ (10 microM) did not affect isoproterenol (10 nM)-induced relaxations. In conclusion, these results provide evidence that NO is involved in NANC nerve-induced relaxation and the participation of VIP (and related neuropeptides) cannot be excluded in causing relaxation of mouse gastric fundus muscle strips. These findings support the idea that VIP directly stimulates the production of NO by increasing NOS activity and thereby activating soluble guanylyl cyclase in smooth muscle.

Abstract
We examined the characteristics of the non-adrenergic non-cholinergic (NANC) nerve induced relaxation and the possible interaction between nitric oxide (NO) and vasoactive intestinal polypeptide (VIP) on the basal tone of the circular muscle of the rat gastric fundus. Electrically induced NANC relaxations were partly inhibited by N(omega)-nitro-L-arginine (100 microM), whereas sodium nitroprusside (SNP; 10 microM) and VIP (5 nM) induced relaxations were not affected. 2-Amino-5,6-dihydro-6-methyl-4H-1,3-thiazine (AMT; 5 microM) also inhibited the responses to electrical stimuli to a similar extent as N(omega)-nitro-L-arginine but not VIP. However, AMT plus N(omega)-nitro-L-arginine did not give an additional inhibition above that of each drug alone on NANC relaxations, and dexamethasone (10 microM) had no effect on NANC nerve induced relaxations. 1H-[1,2,4,]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ; 10 microM), a selective inhibitor of guanylate cyclase, abolished the responses to NANC nerve stimulation and SNP, while VIP responses were not influenced. N-ethylmaleimide (100 microM), an adenylate cyclase inhibitor, attenuated relaxations to NANC nerve stimulation, VIP and isoproterenol (1 nM), while having no effect on those to SNP, but in combination with N(omega)-nitro-L-arginine, there was no additional inhibition on the responses to nerve stimulation. Alpha-chymotrypsin (10 u ml(-1)) severely diminished VIP induced relaxations, but did not reduce electrical responses. In conclusion, these results suggest that NO is involved in the relaxations induced by short-term electrical stimulation. However, another possible unidentified transmitter that can trigger the accumulation of cyclic GMP is not entirely ruled out and there is no interaction between NO and VIP in the circular muscle strip of the rat gastric fundus, even in the basal state of the tissue.

Abstract
We investigated whether exogenous nitric oxide (NO) donors have a prejunctional and/or postjunctional inhibitory effect on the nitrergic responses and whether this inhibitory effect was mediated by NO itself and in part, by cyclic GMP in mouse duodenal strips. N(omega)-nitro-L-arginine inhibited relaxations induced by electrical field stimulation of nitrergic nerves, but not those with acidified NaNO2. Furthermore, 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ) inhibited both types of relaxations while 2-amino-5,6-dihydro-6-methyl-4H-1,3-thiazine (AMT) and N-ethylmaleimide were ineffective. NO donors, nitroglycerin and sodium nitroprusside, inhibited relaxations induced by nitrergic nerve stimulation, but not those with acidified NaNO2. Hemoglobin, exogenous Cu(2+)/Zn(2+) superoxide dismutase, diethyldithiocarbamic acid and pyrogallol did not influence the relaxation with nitrergic nerve stimulation. However, hemoglobin, diethyldithiocarbamic acid, pyrogallol and diethyldithiocarbamic acid plus pyrogallol attenuated the inhibitory effect of NO donors on relaxation with nitrergic nerve stimulation, and exogenous superoxide dismutase potentiated this inhibitory effect. Moreover, nitrergic nerve-mediated relaxations were inhibited by 8-bromo-cyclic GMP, but not by 8-bromo-cyclic AMP. These results suggest that exogenous NO donors have a prejunctional inhibitory effect on the nerve-mediated nitrergic relaxation and that the inhibitory effects of nitroglycerin and sodium nitroprusside are NO-dependent, but not related to NO metabolites such as peroxynitrite or a nitrosothiol intermediate. However, a contribution of S-nitrosothiol formed intracellularly cannot be entirely ruled out. Also, this prejunctional inhibition is mediated, at least in part, by the cyclic GMP, but not the cyclic AMP, pathway.

Abstract
We evaluated the clinical experience of 115 women with early stage cervical cancer who had been operated in our Gynecologic Oncology Clinic. Of these, 85 were in stage I, and 30 in stage II. Intraoperative complications occurred in 16 patients including 3 cases concerning bladder, 1 ureter, 1 aorta, 5 v.cava inferior, 1 internal iliac a., 3 internal iliac v., 1 obturator nerve and 1 rectovaginal septum hematoma formation. Postoperative complications were observed in 38 patients. These were 14 bladder dysfunctions, 10 lymphocyst formations, 6 urinary infections, 12 wound infections, 3 pelvic infections, 2 eviscerations and 1 incisional hernia. However, no death occurred due to intraoperative or postoperative complications. Pelvic lymph node metastases were observed in 32 patients of whom 17 had only unilateral involvement, most often in the obturator region. Para-aortic lymph node metastases were diagnosed in 4 patients, all of whom were in stage II.

Abstract
The present study was undertaken to investigate the postsynaptic effects of aminoglycosides on contractions evoked by acetylcholine (ACh), KCl, electrical field stimulation (EFS) and Na(+)- and Ca(2+)-free Ringer solution with 0.2 mM Na2 EDTA (NaFCaFR) in the isolated frog rectus abdominis. Neomycin inhibited contraction elicited by ACh, NaFCaFR, and EFS at the higher frequencies (8 and 10 Hz) but not those elicited by KCl and EFS at the lower frequencies (2, 3 and 5 Hz). D-tubocurarine inhibited ACh-induced contractions in a concentration-dependent manner. In addition, drug reduced EFS-evoked contractions to a limited extent. Lower concentrations (10(-5), 5 x 10(-5), 10(-4), 2 x 10(-4) and 3 x 10(-4) M) but not higher concentrations (4 x 10(-4) and 5 x 10(-4) M) of methoxyverapamil exhibited a concentration-dependent inhibitory action on NaFCaFR-induced contractions. Similar inhibitions of the same type of contraction were displayed by aminoglycosides (neomycin, streptomycin, netilmycin, gentamycin and amikacin). These results suggest that in addition to their antagonistic action on nicotinic receptors in the frog rectus abdominis, aminoglycosides may exert stabilizing effects on some functional components contributing to contractions at the membrane.

Abstract
Choledochal cysts are an uncommon anomaly of the biliary system manifested by cystic dilatation of the extra or intrahepatic biliary tree or both. It is most frequently found in Orientals and in females. Endoscopic retrograde cholangiopancreatography is a valuable imaging technique in the diagnosis of choledochal cysts in adults. Additionally, in selected cases, a choledochocele may be effectively managed by endoscopic sphincterotomy. We present clinical and endoscopic findings of six adult patients with choledochal cysts. Clinical symptoms were characterized by abdominal pain, jaundice and cholangitis. Associated hepatobiliary pathologic findings included cholelithiasis, recurrent acute pancreatitis, gallbladder carcinoma, Cystolithiasis, choledocholithiasis, biliary stricture and hepatic abscess.

Abstract
Between 1983 and 1990 a total of 74 freestyle mountaineers and 88 mountaineers with skis attempted to climb Mount Agri (Ararat). From the freestyle group two mountaineers were affected by acclimatisation disorder at 3200 m and seven at 4200 m above sea level. Acute mountain sickness (AMS) affected four mountaineers at 4200 m, eight at 4700 m, two at 5000 m and two at 5165 m, while 49 reached the summit. Only one of the mountaineers with skis was affected by AMS (at 4200 m), while all the others reached the summit. The symptoms of acclimatisation disorder and AMS, according to their degree of frequency, were headache, weakness, dyspnoea and palpitation, anorexia, nausea, vomiting, giddiness, ataxia and insomnia. Pulse rates varied between 115 and 124/min, and breathing between 30 and 38/min.

Abstract
Pica is defined as the compulsive eating of anything and has been known for more than a hundred years. It is a worldwide problem which can be seen in every race, age, sex and geographic region. Its true incidence is not known and may be greater than expected. Although it is a widespread phenomenon, the causes and risk factors of pica are not well established. Clinical signs and symptoms of pica syndrome are numerous but liver disorder associated with this syndrome is not widely reported. We reported here liver disorder possibly related with pica.
